the present study was aimed to investigate the effects of titanium dioxide nanoparticles (nano-tio 2 ) on wheat ( triticumaestivum l.) plants cv. parsi. the experimental treatments included seven concentrations of nano- tio 2 (10, 100, 1000, 1200, 1500 and 1700 ppm nano-tio 2 and control (without any tio 2 ). the results showed that among the wheat germination indices, germination rate and weig...

Considering forage grass species, germination is one of the important stagesconcerning the growing stage that is often influenced by environmental stresses,particularly salinity and drought stresses. Thus, this study aims to assess the effects ofsalinity and drought stresses on germination characteristics and seedling growth of desertwheatgrass, Agropyron desertorum (Fisch. ex Link) Schult. in ...

The objective of this paper was to evaluate the effect of nitric oxide (NO) as a protecting agent of sesame seeds submitted to different concentrations of cadmium. The treatments were: water (control), water increased by sodium nitroprusside (SNP) and other treatments regarding the concentrations of cadmium increased by SNP. The following determinations were done: germination, first count of ge...

to answer this question that if osmopriming improve germination indices in salinity-affected seeds of pinus eldarica medw., a factorial experiment in randomized completely design was carried out with three replications. osmotic treatments were applied in 5 levels (-2, -4, -6 and -8 bar for 72 hours and non-primed) by polyethylene glycol (peg) and salinity treatments in 8 levels (0, 40, 80, 120,...

The effect of different pre-sowing seed treatments and sowing dates on germination and rootstock quality of ber was assessed to standardize a combination which could yield optimum germination and quality rootstock. Of the fourteen pre-sowing treatments, highest seed germination and best seedling growth was obtained in T10 x D2 (seed soaking in water for 48 hours followed by 6 days storage in mo...

Damask rose (Rosa damascena Mill.) has high economic importance and commercial value. The plant essential oil is used for perfumery, food and medicinal industries. It is necessary to know much about seed germination for study of genetic variation and breeding improved varieties of R. damascena. In this study seed germination of R. damascena were evaluated, using thermal period treatments. The d...

abstract. seeds or plant organs are usually used as the materials for the long-term cryopreservation. the aim of this study is to investigate the possibility of seed cryopreservation of lilium ledebourii (baker) boiss. as an endemic and endangered species because of genetic erosion. to evaluate seed potentials for the cryopreservation, four treatments including vitrification, 30% glycerol, desi...
